Design of solar generator
The technical data of the selected solar generator
must be within the Solar Inverter‘s specifications
(see Technical Data). Incorrect dimensioning can
lead to reductions in the yield and to destruction of
the device.
The design program Sunways Sundim may be help-
ful to you. Sunways Sundim is available on the
included CD-ROM or at our homepage
www.sunways.de.
Be sure to take the following points into account
before planning your system:
· Watch the celestial alignment of the modules.
A maximum yield is achieved in Central Europe
with a module slope of 30° to the vertical and
direction of the solar generator field directly to
the south.
· The output of the cells decreases as the module
temperature increases. Install your solar genera-
tor with sufficient ventilation from behind.
· Check your solar generator approx. every three
years for soiling. This occurs especially on the
lower edge of the modules and forms a veil
that cannot be washed off even by heavy rain.
Reduced yield can be prevented by cleaning with
a wet cloth or a brush.
· Avoid switching off individual modules or solar
cells of your system. This can lead to major
decreases in yield.
